FIRE-ESCAP SPECIFICATION forming part of Letters Patent No. 289,163,dated November 27, 1883.

Application filed October 1, 1883. (No model);

To all whom it may concerm- Be it known that I, LEO STRAEHL, of Detroit,in the county of IVayne and State of Michigan, have invented new anduseful Improvements in Fire-Escapes; and I hereby declare that thefollowing is a full, "clear, and

exact description thereof, reference beinghad to the accompanyingdrawings, which form a part of this specification.

This invention relates to certain new and useful improvements in theconstruction of fire-escapes, by means of which aperson may lowerhimself from the upper portion of a building with perfect ease andsafety; and the invention consists in the peculiar construe-e tion,arrangements, and combinations of the parts, all as more fullyhereinafter set forth.

Figure 1 is a perspective view of my im-v proved device as in use. Fig.2 is an elevation.

In the accompanyingv drawings, which form a part of this specification,A represents a tube, which may be formed solid or in two parts andsecured together by suitable screws,

and bent into the form of an S, as shown,

This tube A is provided with studs a, and in these studs I properlyjournal the grooved friction-wheel B, which has slotted hearings in saidstuds, and to other studs, 12, I pivotally secure one end of the leverC, the opposite or free end of which is perforated and slips over thescrew-stud D, which latter receives upon its outer end the winged nut E.

Upon the lower side of this tube A, I form a loop, 0, into which isrigidly secured one end of the strap F, the opposite end of which isprovided with a snaphook, designed to engage with the ring (1 upon thewaist-belt G, which is buckled around the person using the 0 device. i

H represents a rope, one end of which is passed through the tube A, andcarries upon that end a'hook, I, which is likewise designed to be hookedinto the ring 01.

In practice the belt is buckled around the 5 waist of the persondesiring to escape from the building, with the ring (I in front, and thestrap F and rope hooked into this ring. The loop formed by the ropebetween the ring d and the tube A is then passed through the properhook, J, which should be rigidly or firmly screwed into the floor orother convenient part ot the room. The person now lets himself out ofthe window, and governs the rapidity ing the tube in his hand, asshown'inthe drawings, and compressing the grooved frictionroller uponthe rope by means of the lever, and it can readily be seen that theoperator can easily stop himself at any desired point. A

This device is simple in its construction, and can readily be rolled upinto a small compass and carried in a valise. It will be seen that,independent of the friction device proper, there is a large amount offriction, due to the rope passing twice over the window-sill and aroundthe hook J.

I am aware that S-shaped. tubes with friction devices are not new infire-escapes, and therefore do not claim, broadly, such construc- 7otions.

hat I claim as my invention is' In combination with the belt G, strap F,and rope H, the S-shaped tube A, provided with the groovedfriction-wheel B, regulating- 7 v lever C, screw -stud D, and nut E,substantially as and for the purposes specified.
